But it was still special having the boys just less than 11 hours apart.

The sisters were a few rooms apart at York Hospital, their own mother running from one to the other, Bender said. The hospital photographer took photos of the babies together. The sisters, both released from the hospital over the weekend, pushed their babies down the hallway together.

And who better to share pregnancy's ups and down with than a sister?

"We were both very hormonal," Clayson said. Since they were only a month apart, she said, they were going through pretty much the same things at the same time. "We could relate a lot. It was a nice bonding experience."

Bender and her husband Jamie have another son, Cayden, 3. Clayson and her husband Jeffrey have three other children, Jaylinn, 5, Arianna, 3, and Jeffrey Jr., who is 23 months old.

And there will soon be another baby cousin. Bender and Clayson have a sister-in-law due with a boy in May. All of the kids are very close, Bender said.
